Just a few days ago we showed you Ice Cream Sandwich running on the HTC Vivid. That was an official OTA release from HTC and ATT for their big screen Android LTE phone. What about its launch-mate the Samsung Galaxy S II Skyrocket? No official love yet, but DesignGears, a ROM developer who hangs on XDA Developers got his hands on a genuine Samsung ICS ROM for the Skyrocket and made it available to us all. It's very polished and feature complete, and I've had no functionality problems with my personal Skyrocket since flashing it.

But keep in mind that this isn't the official upgrade and things might not go as smoothly for you. It will wipe out all data on your phone, so back up your data and be prepared to set up your Skyrocket from scratch. Take the microSD card out too, because that might get wiped by the upgrade process. Battery life seems to be shorter with this pre-release ROM, and the phone gets a little warmer when working hard. That said, DesignGears made it very easy to upgrade your phone, and he's packaged Odin (the flash upgrade for Samsung phones) and the ICS Rom into one easy exe (yes, it's Windows only at the moment). You do not need to root your phone, but if your phone is already rooted, you'll need to re-root it after the upgrade to Android OS 4.0.3.

You'll notice that Samsung went with a heavy dose of TouchWiz, and we can't help but feel they went a little Hello Kitty on poor Android 4.0. But we also demo the phone running with the Nova Launcher, for those of you who prefer a more pure Android ICS look.
